I remember when I used to go to the States on business and drive cars all over the place, that there were warning signs at bridges "remember bridges freeze first".

Re: Dew Point In Simple Terms
evaporative cooling is much more pronounced on bridges--greater surface area (above and below), low thermal mass (heat reserve from the day). --its a bit like the wet finger in the air to determine wind direction. The energy transferred is significant-for illustration---it takes the the same energy to evaporate one cc of water at 100 deg C from liquid to vapour as it does to raise one cc of water from 0 deg C to 100 deg C--the old term is latent heat of vaporisation.In this case the cooling effect of the evaporation is significant--hence the freezing . For motorcycling thats why it feels that much colder on a cool, damp day--water is evaporating off your surface due to air flow ---sucking the heat from you--much worse than a simple cold, but dry day. I have seen such signs here in the UK also.Dark Knight wrote: ↑Tue Nov 05, 2019 6:15 pmI remember when I used to go to the States on business and drive cars all over the place, that there were warning signs at bridges "remember bridges freeze first".
